Rabbi, Talmudic Scholar and Kabbalist
"It is especially important to express your feelings of joy when giving charity to a poor person. Show the person you are glad to be able to help him out. Showing displeasure giving charity erases the merit of giving."
"Close friends and relatives should visit someone as soon as he becomes ill; others should wait until three days have passed. If, however, the person is ill, even the latter should come to visit him immediately. If you can't visit, then at least you should call him."
"It is preferable not to visit a sick person the first and last three hours of the day. If, however, you find this difficult, you may visit him any time during the day as long as it is convenient for the person."
